Quick Start

Traefik is a dynamic reverse proxy. It automatically discovers services running in Docker or Kubernetes and routes traffic to them without requiring manual configuration reloads.

docker-compose up -d

Production Patterns

Docker Label Routing

When running a Docker Swarm or Compose cluster, you do not write Traefik configuration files. You simply attach labels to your application containers (traefik.http.routers.my-app.rule=Host('example.com')). Traefik dynamically detects the container and routes traffic.

Architecture & Scaling

Kubernetes Ingress

Traefik natively implements the Kubernetes Ingress specification. It seamlessly reads your Ingress objects or custom IngressRoute CRDs and dynamically updates its routing table.

Error Recovery

Traefik includes an internal dashboard on port 8080. If routes are failing (404), check the dashboard to ensure Traefik has successfully discovered the container and parsed the routing rule correctly.

Security Notes

Traefik supports automatic Let's Encrypt generation. When running multiple Traefik replicas in Kubernetes, you must use a distributed key-value store (like Consul) to store the TLS certificates, otherwise replicas will hit ACME rate limits.

Why use this skill

Use this when your agent works with traefik — structured patterns beat pasted docs and prevent common hallucinations.

AI pitfalls

• Hardcoding region or account IDs
• Missing IAM least-privilege on cloud resources
• Confusing similar service names (e.g. S3 vs CloudFront)

Production checklist

• Secrets in environment variables, not source code
• Error handling and logging in place
• Rate limits and timeouts configured
